If you are looking for genuine Kona Cotton, you need to find the Kaufmanns name on the bolt. The other stuff is just a copy. 10.00+ is way too high a price to pay for Kona cotton even with the name Kaufmann. Your LQS is ripping you off.
I can find the genuine stuff at Hobby Lobby for about 6.99 or 7.99 and use a 40% off coupon.
